Antibiotic prescription patterns among Swedish dentists working with dental implant surgery: adherence to recommendations

摘要

To investigate antibiotic prophylaxis prescription behaviors among Swedish dentists working with dental implant surgery and the influence of scientific reviews. Material and methods: An observational questionnaire study was conducted in 2008 and 2012. Dental clinic addresses were found through online search services of Swedish telephone directories. The questionnaires were posted to eligible dentists (120 in 2008, 161 in 2012) in the Stockholm region, Sweden. Absolute frequencies were used to describe the data. Chi-square tests were applied to assess statistically significant differences.Results: The response rate was 75% in 2008 and 88% in 2012. In 2008, 88% of the dentists routinely prescribed antibiotic prophylaxis when performing implant surgery and 74% in 2012 (P = 0.01). There was a significant reduction in the dentists prescription patterns as 65% prescribed a single dose in 2012, compared to 49% in 2008 (P = 0.04). Amoxicillin was the drug of choice for 47% of the respondents in 2012, and 21% in 2008 (P = 0.01). Dentists without postgraduate clinical training were significantly more prone to extend antibiotic administration after surgery (P < 0.009). Conclusions: There is a wide variation in the choice of compound and prescription patterns of prophylactic antibiotic prior to implant insertion. A reduction in antibiotic prescription to a single dose was observed comparing 2008 and 2012, probably influenced by scientific reviews. Dentists with postgraduate education are more likely to limit antibiotic usage.
